Champions League Matchday 3 vibe check: Barcelona and Bayern impress; Manchester United in trouble

The Champions League shifts into midseason mode this week with a Matchday 3 slate full of showdowns that will test the tournament's leading contenders. On Tuesday, Barcelona visit Paris Saint-Germain in the headline clash, while on Wednesday Bayern Munich host Arsenal in a meeting between two knockout-stage regulars. Not everyone is riding the same wave, though: Manchester United remain stuck in a rut and head to Italy for a tricky game against Como.

• Hansi Flick's Barcelona arrive in Paris with their best attacking form and a sturdier defense than in recent seasons.
• Bayern Munich snapped a two-game winless run with a 6-1 thrashing of RB Leipzig before facing Arsenal.
• Arsenal edged past Nottingham Forest and relied on their bench strength ahead of the trip to Munich.
• Manchester United cannot find a way out of their slump and visit Como with another stumble looming.
• Italian clubs went winless on Matchday 2 and are looking to improve their standing in the third round.

Flick's Barcelona and Lamine Yamal face a Paris test

For years, Barcelona were the neutral's problematic favorite: financial trouble and a worrying tendency to concede goals. Under Hansi Flick, they remain must-watch viewing, but for entirely different reasons. The chaos has been replaced by classic entertainment, with Lamine Yamal leading the show week after week.

The 19-year-old winger followed up two assists on European Matchday 2 with a goal and an assist in the 5-2 win over Real Betis. His strike from the edge of the area summed up his skill set: a rocket of a shot paired with elite creativity. That attacking brilliance is now backed by a defensive resolve the club had not shown since before the German coach arrived.

More than a decade has passed since Barcelona last lifted the Champions League trophy, but this season looks like their best chance in years to return to the summit. Tuesday's trip to the French capital will put that idea to the test against a PSG side that remains the team to beat.

Bayern Munich rediscover their scoring touch before Arsenal clash

Vincent Kompany's Bayern share a few traits with Flick's Barcelona, including a tendency to switch off at the back. The difference is that the Bavarians usually survive those lapses thanks to their sheer firepower, with Harry Kane and Michael Olise among the most watchable players in the game.

That does not mean the defensive mistakes have come without a cost. Manuel Neuer's risky approach put them in early trouble at Augsburg, where they only rescued a point, and the 3-3 draw on European Matchday 2 added to the concerns. But Bayern have a habit of responding when their backs are against the wall: after two straight draws, they routed RB Leipzig 6-1, a major confidence boost before Wednesday's meeting with Arsenal.

Arsenal lean on their bench before the Munich trip

Sunday's win at Nottingham was far from glamorous, but Arsenal will take it. They sit three points behind the Premier League leaders and head to Munich without major pressure. Kai Havertz and Bukayo Saka found themselves stumped by a Forest defense sturdier than the results suggest, but squad depth solved the problem.

Noni Madueke came off the bench to score the winner, a reminder that depth will be crucial in the most demanding fixture of the round. The visit to the Allianz Arena will test the maturity of a side aiming to make a definitive leap in Europe.

Manchester United stuck in crisis and facing an unpredictable Como

Manchester United cannot seem to solve their problems, with mediocrity becoming their defining quality. The underlying Premier League numbers suggest they should be higher than 13th, but their attack sputters constantly and their defense leaks just enough to dig them into holes.

The feeling that another imperfect day is around the corner follows the Red Devils everywhere, no matter the occasion. Wednesday's trip to Como will be worth watching for that reason, even if the opposition are not among Serie A's elite. The Lisandro Martinez episode, with the defender forced into an apology, captures the tense mood around the squad.

Italian clubs are struggling to deliver in the Champions League

Italian football has enjoyed few good days in recent years, and its clubs are now feeling the strain in the Champions League. On Matchday 2, none of the Serie A representatives won: Roma let a 3-1 lead slip against Real Madrid, Inter fell to Club Brugge, Napoli could not get past Villarreal and Como lost at Feyenoord.

Matchday 3 offers room for improvement, though with no guarantees. Inter should be favored against Shakhtar Donetsk and Roma are expected to beat Slovan Bratislava. Como have an intriguing opportunity against a shaky Manchester United, while Napoli face a Bodo/Glimt side capable of making life difficult for anyone.
